# Unrelenting Infection of Implanted Prosthetic Hip Joint by Corynebacterium striatum

## TL;DR

This paper describes a persistent infection in a hip implant caused by a multidrug-resistant Corynebacterium striatum, highlighting the growing clinical significance of non-diphtherial corynebacteria.

## Contribution

The novelty lies in reporting a rare and persistent prosthetic joint infection caused by a multidrug-resistant Corynebacterium striatum.

## Key findings

- Corynebacterium striatum caused a non-healing infection in a prosthetic hip joint.
- The infection was multidrug-resistant, complicating treatment.
- NDC species are increasingly recognized as clinically significant pathogens.

## Abstract

Non-diphtherial Corynebacterial (NDC) species, while previously considered as culture contaminants, are increasingly being implicated in clinical disease and identified as causes of opportunistic infections. In cases where they grow in pure cultures, isolated from a sterile site or repeated isolations from the same patient, NDC may be labeled as clinically significant. We report here a case of non-healing infection of one of the implanted devices in a case of bilateral total hip replacement, caused by multidrug-resistant Corynebacterium striatum. Adherence to infection prevention strategies is essential for the prevention of prosthetic implant infections.
